JOHN VAN EPS, OF' SOMERVILLE, NEV JERSEY.

MUSIC-LEAF TURNER.

EPECIFICATION forming part of Letters Patent No. 349,540, dated September 2l, 1886.

Serial Xo. 199,480. (No model.)

To @ZZ whom t may concern.:

Be it known that l, JOHN VAN EPs. a citizen of the United States, residing at Somerville, in the county of Somerset and State of New Jersey, have invented certain new and useful lmprovements in Music-Leaf Tnrners; and I do hereby declare that the following is a full, clear, and ex act description of the same, reference being had to the annexed drawings, making a part ol' this specification, and to the letters and figures of reference marked thereon.

Figure l. of the drawings is a perspective View of my improved music-leaf turner, showing` it applied to what is known as the umbrella illusie-stand, used in bands or orchestras; Fig. 2, a similar' view of my invention, showing it adapted for use on a piano or organ; Fig. 3, a detail perspective view of the supporting-bracket and its attachments; and Fig. J., a detail under plan view of the snp porting-lnacket and spring-latch device connected thereto, and a portion of the key-plate for operating the latch, shown in dotted lines.

The present invention has for its object to provide a simple and effective device for turning the leaves of sheet or other music bound in book form, and a device that will be durable, not easily got out of order, can be mannfaetnred at a comparatively small cost, and a device that will be positive and cert-ain in its action, which objects l' attain by the construetion substantially as shown in the drawings, and hereinafter described and claimed.

ln the accompanyi ng drawings l have shown in Fig. l. what is termed an umbrella musicstand;7 consistingof the musiesupport A, adjust-ably connected to the upper end of a rod, a, which is extensible within a tubular standard, D, and held in its adjusted position by set-screw I). This standard B is provided with hinged or pivoted tripod-legs c, held extended by detachable braces (l, pivotally attached to the legs and engaging with the lower end of the standard.

The above is one of many forms of musicstands to which my invention is applicable, and is shown simply to illustrate the application and use of the mechanism for turning the leaves of the music, which is connected to an adjustable and removable bracket, C, upon the musiesupport. To this bracket is pivotally attached a series of arms, D, provided at their outer ends with upright leaf-holding devices E, consisting each of two wires, between which the leaf is placed and held. Any desirable number of these arms D, with the leaf-holding devices E, may be employed, and previous to turning the illusie-leaves and before commencing a piece ofmnsic the leaves are all held upon one and the same side of the music-leaf sup port A, as shown in Fig. l. This is attained by a spring-latch device, F, pivotally attached to the end of the bracket C, which holds together the arms D and devices E, between which the leaves are inserted. Vhen it is desired to turn over one of the musicleaves, the latch F is depressed, which releases the upper one of the seriesof arms D, and immediately thereafter a suitable spring, c, (one being employed for each of the arms,) will automatically carry the arm to the opposite side of the support A, and with it the leaf of music. This latch F consists of a flat metal plate recessed to form a keeper, Z, for retaining the arms D together preparatory to turning the leaves, and is also formed with a cam, in, so that when bringing the arms back to their normal posi tion they will be raised as the arms come in contact with the inclined face of the cam, and thus automatically engage with the keeper as the arms pass beyond the cam, this construetion of the latch heilig considered of great importance to the successful operation of the device. y

As a means for operating the latch F, l have shown in Fig. l a cord, j', extending down to one of the tripod-legs c, and connecting with a foot-pedal, g,- but any other desirable and convenient means may be employed for operating the latch by the foot or by the hand, the latter being effected by the use of a key-plate, G, which may be detachably connected to the latch in any desirable manner. After the latch F has been depressed it resumes its normal position by means of the spring 7i, to hold the remaining ones of the arms D together, and for this reason l term the latch a spring-latch device.7

I do not desire to confine myself to any particular means of pivotally connecting the arms D to the bracket C; but in the present instance I prefer providing the end of each arni with a collar or sleeve, t', to fit over a postupon the bracket.

It is evident that many changes or modifications in the details of construction as would come Within ordinary mechanical skill may be made without departing from the principle of my invention, and I therefore reserve this right and the right to apply the device for turningA music or other leaves, and to whatever uses .it may be found applicable.

In Fig. A2 I have shown my invention adapted for attachment to a piano or organ, the music-support being shown at I, and provided with hangers K, to catch on a piano or organ, the bracket C being attached to the support in any suitable manner. Near the center of the support I are connected two upright parallel rods, L, to place sheet-music between, to keep the leaf-turners from throwing it ofi' the support.

with feet k, to take the weight of the attach'- ment off the hangers K, and make it more steady when operated. p

The hangers K and rods L may be detachably connected to the support I, or adapted to close down thereon when not in use, to make the device compact.

The support' I is providedy Having now described my invention, what I 3o claim as new, and desire to secure by Letters Patent, is-

l. In a leaf-turner, a removable and adjustable bracket provided with a series of arms carrying holding devices for the leaves, and 35 kSprings for automatically operating the arms,

in combination with a spring-latch device pivoted to the bracket and consisting of a metal plate recessed to form a keeper to hold the arms together upon thel side of the bracket, 4o and having a cam to raise and guide the arms -to'the keeper, and suitable means for operating or depressing the latch, substantially as and for the purpose set forth.

2. In a leaf-turner, a suitable support pro- 45 vided with legs, in combination with hangers and two parallel upright rods, between which the sheet-music is held, as specified.

Y I'n testimony that I claim the above I have hereunto subscribed my name in the presence 5o of two witnesses.
